Abstract

The present study aims to report the sudden death of two captive individuals of the Burrowing Owl Athene cunicularia that coexisted in the same enclosure with other raptor birds in a Zoo of Brazil. Despite Haemoproteus infections generally being considered benign, they can lead to sudden death, particularly in stressful environments. Through hematological examinations and microscopic analyses, this article reports two cases of Haemoproteus in Burrowing Owls, suggesting a potential correlation between its presence and owl’s deaths. Also, discusses the prevalence of this infection in captive raptorial birds, emphasizing the significance of immunity and proper management to prevent infections and reveal the importance of early diagnosis for the preservation of the health of these captive birds.
